Mosques in New York City are struggling to house and feed migrants as the country’s latest immigration surge becomes increasingly more African and Muslim. Leaders of a mosque in Harlem say their congregation is spending hundreds of dollars a night to host iftar, the traditional end of fast meal during Ramadan. An imam in the Bronx has turned the home that houses his mosque into a makeshift shelter for migrants. The challenge has become all the more pronounced during the holy month that ends next week. Mosque leaders say they’ve stepped up their appeals for money, food and other donations.
